Reuse of Excavated Soil <br /> Because this affected soil does not pose an unacceptable risk to human health or the environ- <br /> ment, it can be reused at the site. However, a petroleum hydrocarbon odor and crude oil residue <br /> may be present in this soil; therefore, consideration should be given to where the soil is placed. <br /> Potential reuse options include placement of the soil back into the subsurface (e.g., in trenches <br /> and other excavations) or underneath surface coverings e.g., roads, parking areas, or other paved <br /> structures). The following guidelines are recommended: (1) if used as trench backfill, do not <br /> place affected soil in contact with underground utilities' (2) do not place affected soil as backfill <br /> for excavations if geotechnical properties are insufficient; and (3) do not place shallower than 2 <br /> feet below ground surface unless covered by pavement. <br /> If affected soil cannot be reused in the subsurface or underneath surface coverings, the soil <br /> should be stockpiled separately from other non-affected soil excavated at the site, and CPL <br /> should be contacted (see contact list on last page). If re uired by a regulatory agency, CPL will <br /> arrange to have the affected soil removed for off-site disposal (e.g., landfill). If affected soil is <br /> disposed of off site without CPL'S involvement, CPL Will not be responsible for any cost or <br /> liability associated with such disposal. In addition, it is important to consult with the disposal <br /> facility regarding potential restrictions for accepting petroleum hydrocarbon-affected soil_ <br /> According to the San Joaquin County Air Pollution Control District, no permit to stockpile this <br /> soil is required by them. <br /> Health and Safety Issues <br /> Because the affected soil does not pose a human health threat based on the Dividend risk assess- <br /> ment, construction workers or others who encounter and handle affected soil do not require any <br /> unique health and safety training above standard requir ments for performing their job. <br /> KAWPDOCSNC34991SOILPLAN.DOC(WORM) 4 <br />
